Answer:
a. A waffle has 16 squares.
In squares there are same number of tiles in rows and columns.
When there are 16 squares that means same number of squares are in rows as well as in columns.
We can write like 4 x 4.
So, a waffle has 4 squares in each row.
b. A magic square has 49 squares.
It is 7 x 7 , so there are 7 tiles in a row.
c. A tile game has 100 squares.
Its is 10 x 10, so there are 10 square in a row.
